Three steps to reduction surgical site infection: presentation of a comprehensive model

To prevent surgical site infections (SSIs), a three-step model is proposed, which integrates perioperative measures, multidisciplinary collaboration, and continuous quality improvement (CQI) initiatives.


Introduction
Surgical site infections (SSIs) are defined as infections occurring up to 30 days after surgery (or up to one year after surgery in patients receiving implants) and affecting either the incision or deep tissue at the surgical site [1].SSIs are a significant concern, as they not only lead to increased morbidity and mortality rates but also impose a considerable economic burden on healthcare systems worldwide.SSIs pose a substantial challenge to patient safety and healthcare systems worldwide.Despite advancements in surgical techniques and infection control measures, SSIs continue to occur at an alarming rate.SSIs are responsible for approximately $3.5 billion to $10 billion in US healthcare costs annually.Compared to patients without SSIs, those with SSIs remain in the hospital approximately 7 to 11 days longer; one study involving 177,706 postsurgical patients reported that SSI was the cause of 78% of all readmissions [2].Therefore, measures to reduce surgical site infection are necessary [3] and must be adaptedunder pandemic situations [4].

Results
The proposed 3-step model integrates perioperative measures, multidisciplinary collaboration, and continuous quality improvement (CQI) initiatives to enhance patient safety and outcomes.

Perioperative measures
This subsection emphasizes the importance of adhering to evidence-based guidelines for infection prevention during surgical procedures.It explores preoperative strategies (e.g., patient optimization, antimicrobial prophylaxis), intraoperative measures (e.g., sterile technique adherence), and postoperative care (e.g., wound management) [1].

Patient optimization
Preoperatively identifying and addressing modifiable risk factors such as obesity, smoking cessation programs, glycemic control in diabetic patients, and decolonization of nasal carriers of Staphylococcus aureus can significantly reduce the risk of SSIs.

Antimicrobial prophylaxis
Administering appropriate antimicrobial prophylaxis based on established guidelines is crucial in preventing SSIs.

Skin preparation
Proper skin preparation using residually-acting alcoholbased formulations that contain e.g.povidone-iodine or chlorhexidine gluconate, significantly reduces bacterial colonization at the surgical site.

Intraoperative strategies Aseptic technique
Adherence to strict aseptic techniques during surgery minimizes contamination risks.

Surgical attire
Wearing appropriate surgical attire including sterile gowns and gloves reduces the introduction of pathogens into the surgical field [5].

Surgical drapes
The use of sterile surgical drapes creates a barrier between the surgical site and potential sources of contamination.

Surgical site irrigation
Antiseptic irrigation solutions, such as polyhexanide or povidone-iodine, can be used intraoperatively to reduce bacterial load at the surgical site.

Wound care
Proper wound care techniques, including regular dressing changes and monitoring for signs of infection, are essential in preventing SSIs.

Early mobilization
Encouraging early mobilization postoperatively aids in improving blood circulation and reducing the risk of infection.

Antibiotic stewardship
Rational use of antibiotics, including appropriate duration and selection based on culture results, helps prevent the development of antibiotic-resistant organisms.

Multidisciplinary collaboration
The role of surgeons Surgeons play a pivotal role in preventing SSIs, for instance, through appropriate antimicrobial prophylaxis, meticulous surgical technique, and timely wound closure.Collaborative efforts with other healthcare professionals can enhance compliance with these practices and promote standardized protocols.

The role of nurses
Nurses are integral members of the multidisciplinary team involved in perioperative care.Their contributions include preoperative patient education, strict adherence to aseptic techniques during surgery, effective wound management postoperatively, and surveillance for early detection of SSIs.

The role of anesthesiologists
Anesthesia providers contribute significantly to SSI reduction by optimizing patients' physiological status before surgery, ensuring normothermia during procedures, and implementing strategies such as antibiotic stewardship programs that minimize the risk of infection.

Infection prevention specialists
Infection prevention specialists play a critical role in developing comprehensive infection control programs tailored to each surgical setting's unique needs.Their involvement includes surveillance, monitoring compliance with infection control practices, and providing education and training to healthcare professionals.

Importance of environmental services
Environmental services personnel play a crucial role in maintaining a clean and hygienic surgical environment.Their collaboration with the multidisciplinary team ensures proper cleaning and disinfection surfaces and validated reprocessing of surgical equipment.

The role of information technology
Information technology systems can facilitate communication, enhance data collection, and support decisionmaking processes related to SSI prevention.Collaborative efforts between healthcare professionals and IT specialists can lead to the development of innovative tools for real-time monitoring, risk assessment, intervention implementation and auditing [3].

Patient engagement
Engaging patients in their care is vital for SSI reduction.Educating patients about preoperative hygiene measures, promoting adherence to prescribed medications, and involving them in shared decision-making processes can empower patients to actively participate in infection prevention.

CQI initiatives
To sustain long-term improvements in SSI rates, this subsection emphasizes the importance of CQI initiatives.It explores the use of surveillance systems, data analysis, feedback mechanisms, and regular audits to identify areas for improvement and implement targeted interventions.

Methodologies employed in CQI initiatives
Various methodologies are utilized in CQI initiatives to reduce SSIs.This section explores the application of Lean Six Sigma principles, Plan-Do-Study-Act cycles, root cause analysis, process mapping, and other quality improvement tools in different healthcare settings.

Outcomes of CQI initiatives
This section presents a comprehensive analysis of the outcomes associated with CQI initiatives aimed at reducing SSIs.It examines reductions in SSI rates, improvements in compliance with infection prevention protocols, enhanced patient satisfaction scores, decreased length of hospital stays, and cost savings achieved through these initiatives.

Conclusions
In conclusion, SSIs remain a significant concern in operating rooms worldwide.However, by implementing a comprehensive model that integrates perioperative measures, multidisciplinary collaboration, and CQI initiatives, healthcare institutions can effectively decrease the incidence of SSIs and improve patient outcomes.
